为了保证冷轧薄板的质量,带材在进入五机架轧制之前必须进行酸洗,以避免开卷矫直时氧化铁尘飞扬,造成空气和全线设备受到污染。带钢自动喷洗的工作原理,如图1所示。按此工作原理进行运行,即可形成一个很完整的带钢喷洗自控系统。 R421寄存器的实际电路图,如图2所示。
In order to ensure the quality of the cold-rolled sheet, the strip must be pickled before it enters the five-stand rolling to prevent the oxidation of iron dust from flying during uncoiling straightening, resulting in contamination of the air and the entire line of equipment. Automatic strip cleaning works, shown in Figure 1. According to the working principle of operation, you can form a very complete Strip Spray wash automatic control system. R421 register the actual circuit diagram, shown in Figure 2.
